Description
At present, there is a lack of experimental data constraining the strange nucleon PDFs' dependence on the parton momentum fraction and the weak mixing angle's low-$Q^2$ behavior. The parity-violating asymmetry from the neutral-current deep inelastic scattering of electrons from proton and deuterium targets, which will be measured by the upcoming SoLID experiment at Jefferson Lab, possesses a unique sensitivity to the strange PDFs and electroweak parameters of the standard model. In this talk we explore these sensitivities and perform a global analysis incorporating pseudo-data from simulations based on SoLID experimental projections with radiative corrections to the asymmetry, for the unpolarized PDFs and weak mixing angle. We find a sizable constraining power of future $A_{\rm PV}$ data on the high-$x$ behavior of the nucleon strangeness and an unprecedented resolving power on the weak-mixing angle at low-$Q^2$.
